To all whom, it mag/concern Be it known that I, HERMANL. WAG a citizen of the United States, residing in Mount Vernon, in the county of Westchester 8J1d'St&t6 OffN6W YO1'k have invented cer tain'newiand useful Improvements in Type- Writing' Machines, of which the following is a specification.

:This invention relates-to the mechanism of type; writing .machines which vibrates the. ribbon 'to' cover and uncover the printingpoint at the type-strokes. Usually the ribbon is threa through a carrier, and the latter is connected to alever which is vibrated at each type-stroke, this movement being effected by means of an actuator,

- .which is mounted upon the usual" universalbar frame and connected tov said lever.

The principal object of my invention to provide inexpensive and convenient means for silencing the ribbon-carrier at will, so that it shall not operate during the t pestrokes, whereby the types may print oil the ribbon for stenciling and'other work. 1 For 7 this purpose I mount a Wrist upon said lever 1n such a manner that the wrist may be moved in axial direction to disconnect it from said actuator, and-I connect to this wrist a finger-piece, whereby the operator may conveniently unship the wrist, this finger-piece so connected-that it does not interfere with the Vibrations or the lever when I connected to the actuator.-

In the accompanying drawings, Figure 1. is a perspective view of a ribbon-v brating mechanism of an Underwood front-strike writing-machine, showing the ribbon-vibra tor opera'tively connected to the actuator, so

that the ribbon is thrown ,up to cover the printing-point at each type impression, the

parts being shown in'norrnal position. Figi 2 1s a similar view showing the ribbon-vibrator silenced by reason of a disconnection thereof from the recipro'catory actuator, a type-barbeing shown in printing position and printing off the ribbon.

Types 1 upon the front ends of type-bars2 strike against the front sidof the platen 3, said type-bars being'pivoted at ,4 and having heels 5 to press rearwardly a curved universal bar 6, the latter'fixed upon a reciprocat ing frame 7. Erected upon said frame is an. actuator 8, having avertical slot 9 to receive a 10, rovided: upon a short arm 11 of a lever '12, w 'chiszconnectedat 13-;to an upstanding carrier 14, through which is threaded an ink-ribbon 15. .Sa1dlever is pivoted upon a bracket-16, secured to a rail 17, upon -which travels the framethat carries the.

platen 3, .saidrail 17 forming. part of a frame 18, which is vibrated up and down to 'shift- 1 the platen for writing capital and small letters. The slot '9 in the actuator is sui'liciently high to accommodate this shifting movement.

Thewrist 10 is formed upon the end of a horizontal shaft 19,"Whl0l1 is mounted in a long bearing 01' boss 20, formed upon the 1e ver-a'rm 11, the shaft being slidable through said hearing, so as to withdraw thewrist 10 from the slot 9, Fig. 2, thereby silo lnngthe ribbon-vibrator 14. For convenience inunshipping the wrist 10 I provide upon the op posite end of the shaft 19 a head 21, received in" a cross-fork or slotted member 22, provided upon the end'of a slide 23, the latter havin slots 24 'to receive'guiding-screws 25 and a sohaving a finger-piece 26 projecting at the side of the machine convenient to the operator. Normally the finger piece and slide are pressed in, Fig. 1, so as to maintain the wrist 10 in its normal position in the slot 9, the friction of the slide upon the heads of the screws being sufficient to hold the slide 2,3 wherever it is set. The cross-fork-22 is parallel with the direction of the motion' of the actuator 8, so that the movement of the lever is not interfered with, the head 21 moving idly backward and forward in said fork. .or slotted member.

write off from the ribbon, the finger-piece 26' When it is desired to is drawn out, Fig; 2, unshipping' the wrist 10 from the slot 9, so that the lever 12 and vibrator 14 are silenced. Having thus described my invention, 1 claim 1. In a typewriting machine, the combi-- nation of an actuator having a slot, a ribboncarrier, a lever therefor, a wrist engaging said slot and slidable in said lever and having a head, aslide'having a cross-slot en aging said head, and a finger-piece upon said slide, the latter movable to disconnect said wrist from said actuator, to silence saidvibrator at will; said wrist formed upon a shaft having a long bearing in said lever.
